FOLDABLE srmnc Hammock on cor.

Specification of Letters Patent.

Application filed January 27, 191?. Serial so. a iases.

' citizen of the United States, residing at De troit, in the county ofWayne, State of Michigan, have invented certain new and usefulImprovements 1n Foldable Spring Hammocks or Cots; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference beinghad to the accompanying drawings,and to the characters of reference marked thereon, which form a part ofthis specificatioh.

This invention relates to a foldable spring hammock or, cot adaptablefor usealso as a cradle and kindred purposes, and consists in theconstruction and arrangement of parts hereinafter more fullv set forthand pointed out particularly in e claims.

The object of the invention is to provide a swinging spring cot whereinthe arrangement is such that the supporting braces extending from thebase from which the cot hung, may be readily folded down in the plane ofthe base of the structure and the parts which suspend the cot from saidbraces detached therefrom and folded onto the cot, thereby reducing thewhole to a compact form, provision being made for readily swinging thefolded braces into position for use and connecting the cot supportingparts thereto. The above object is attained by the structure illustratedin the accompanying drawings, in which 2- Figure 1 is a perspective viewof a swinging spring cot involving my invention. Fig. 2 is a perspectiveview of the parts folded. Fig. 3 is a fragmentary view in perspective ofa portion of one of the base strips at the ends of which the brace rodsare journaled. Fig. 4 is a fragmentary view in perspective of a portionof one of the base strips and a portion of one of the brace rods,showing the manner of journaling said rod to said strip. Fig. 5 is afragmentary View in ion: gitudinal section through the end of one of thebase strips, showing the jointed connection between said strip and thebrace rod. Fig. 6 is a side elevation of the apparatus, as shown inFig. 1. Fig. 7 is an end elevation of Fig. 6. Fig. 8 is an enlarged planview of the upper ends of two of the brace rods and the socket memberwhich connects -said rods and affords means for attaching thepivotedlink thereto from wh ch the cot issuspended. Fig. 9 is a side elevationof F 1g. 8. Fig-.10 is a transverse section, as on line l0-10 of Fig. 9.

. Referring to the characters ofreference, 1. designatesthe base stripswhich are located at each end of the frame, and which are adapted torest upon the floor, or other sup porting surface. Each of said stripsis provided with a. central longitudinal rib 2 struck therefrom to addthe necessary strength and rigidity thereto. Crossing between the endsof the base strips are the base rods 3 which form the longitudinalmembers of the bottom of the frame and which at points therein towardeach end are bent at right angles, forming the brace rods 4, there beingtwo of said rods at each end of the frame. To connect the brace rods tothe base strips in a manner to allow the free ends of said rods to swingin the arc of a vertical circle, each of the base strips is provided inthe ends of the rib 2 with half round notches 5 (see Fig. 3), in whichthe rod 3 is adapted. to lie, and with the projecting fingers 6 adaptedto be folded around said rod, as shown in Figs. 4: and 5, whereby tFerod 3 is securely attached to the ends of t 1e basestrips in a manner topermit it to rotate, thereby establishing a pivotal con nection betweenthe brace rods 4 and the base strips of the frame.

The upper ends of the brace rods are bent inwardly at an incline, asshown at 7,'so that said inwardly bent end portions are caused to lieparallel when the free ends of the brace rods are brought together, asshown in Figs. 8 and 10. The parallel end portions of the brace rods areconfined in a member or fitting 8 having parallel sockets'whic h receivesaid endportions 7 and onto which said member is slipped, whereby theupper ends of the brace rods 4: at each end of the frame are detachablycoupled to gether, and provision is made for suspend ing a cot orhammock from the socket members 8 through the medium of theeye or loop 9formed at the inner ends thereof. Coupled to the eye 9 of each of thesocket members 8 by means of a hook it) to swing freely therefrom, is alink 11-, the lower end of said link having a hook 12 which is closedaround the bar of a looped bail 13, the loop of said bail lying in saidhook 12. The free ends of the bail areprovided with hooks 1% which areclosed around theend bar 15 of the cot frame 16 at each end of saidtime.

The frame of the cot 16 as well as the inclined brace rods 4 will beformed of spring material so that when a weight is placed upon the cot,it will spring downwardly and the upper joined ends of the brace rodswill be sprung inwardly, as clearly shown by dotted lines-in Fig. (5.

a il'ording a swinging and resilient support for the occupant of thecot.

This structure is especially adaptable for camping purposes and mar beemployed a porch hammock or as a swinging cradle. The adaptability ofthe parts to be reduced to a small compass. is of material importance intransportation, and the readiness with which the device may be set upwhen required for use renders it an apparatus of great utilit x When itis desired to fold the device, the socket members 8 are withdrawn fromthe ends 7 of the brace. rods, thereby releasing said rods andpern'iitting their free ends to swing downwardly to the position shownin Fig. 2, and by dotted lines in Fig. 7, the bentend portions 7 of saidrods crossing the ends oi. the base strips 1. The cot frame is then.

placed within the center of the folded main frame and the bails l3 andthe Connected links 11 and socket members 8 are folded inwardly, asshown in Fig. 2, thereby confining all of the parts within the area ofthe main frame, in which position they occupy but a comparatively smallspace. The jointed.connection between the cot frame and the hails l3 andbetween said halls and the. links ll. and between said link. and the soket members 3, permit said parts to be.-

lolded within the, cot frame. as described, and is an arrangement whichleaves said parts connected so that when it is desired to set up theapparatus, it may be readily done by swinging the free ends of the bracerods together and inserting the socket members over the parallel endportions 7 thereof. The incline of the end portions 7 of the. brace rodscauses the socket members to bind thereon when weight is applied to thecotl'rame, thereby obviating the liability of the socket ll'ltllllltilfislipping from the projeciing ends of the brace rods. Tho-length of the.socket members is such that when the parts are assembled, the ends ofthe cot frame will swing free of the brace rods. This structure not'onlyaffords the cot frame a swinging motion in all directions but affords avertical springing motion as well.

Having thus fully set forth my invention, what I claim as new and desireto secure by Letters Patent, is

l. A device for the purpose set forth,com-

prising a base frame, end supporting rodspivoted at their lower ends tothe corners of the base frame, their free ends being adaptedv to swingin the arc of a vertical circle, the upper ends of the two supportingrods at each end of the frame having horizontally extending portions,said horizontal portions of each pair of rods bein adapted to lie incontiguous parallelism, in( ependent socket members detachably fittingover the parallel end portions of the supporting rods, and linkspivotally depending from the inwardly extending ends of said socketmembers.

2. A device for the purpose set forth, comprising base strips,longitudinally extending rods journaled to the ends of said strips, theterminals of said rods being bent at rightanglcs to form supportingbraces which swing with said rods as the latter turn in their bearings,the upper ends of the brace rods having bent terminals which are adeptedto lie in contiguous parallelism when the upper ends of said rods arebrought to gether. independent socket members fitting over the parallelterminals of the up 61' end of the brace rods to lock them toget er andhold the longitudinal brace rods from movement in their bearings, andcot supporting links pivotally dcpemling from said socket members.

in testimony whereof, I sign this specification in the presence of twowitnesses.
